To all whom it may concern."

Be it known that I, Evsraca R. Know, a citizen of the United States, residing at Sharon, in the county of Norfolk, State of Massachusetts, have invented a certain new and usefulImprovement in Wrapping-Machines, of which the fOllOWll'lglS a specifica- The invention has relation to machines for wrapping pieces of candy, fruits, and other small articles.

One general object of the invention is to produce a'machine capable of a large output 7 without excessive speed of the working parts 1 thereof. Another'is to produce a machine .of great flexibility in its adaptation to the wrapping of articles of difierent sizes, and

the construction of which shall be simple,

efi'ective, and practical, and not liable to get out of order or to become disarranged by unskilful handling. Special objects of the invention are to provide wrapping mechanism of improvedicharacter; to attain certain desirableresults in the wrapping; and to provide a construction in which the'feeding of a wrapper, the feeding of an article or arti:

' cles for presently being inclosed withinsuch wrappezyand the inw'rapment of a previous article or articles within the wrapper therefor, may all proceed concurrently. Othersare to provide a construction permitting the principal movements-of certain of the main "lqworking parts to be regular and .uninter rupted; also, permitting reciprocatingmovements in the working of .such'parts to be eliminated.

One form of embodimentof the inven-- tion is illustrated in the drawings, in which-- .40

or articles to be iiwrapped, and then perbeen contrived, a1: o, with reference to enabling the employm ent of either one or a plurality of sets of feeding stations, so that while the travelingcarrier is making one plete wrapping operations. Having reference to the drawings,'-

"A rotaltable carrier is represented at A," and :a wrapping-l ead supported and carried thereby is re resented at B, a'stationary wrap ersupply station being represented at and a stationary articlessupply station at D. The function of the wrappersupply mechanism located atthe wrappersupply station is, in general, todeliver a m circuit 'a "givenwrapping mechanism may 1 perform either on: or a succession of comwrapper to the wmppm -headasthe latter passes. The, function 0 the article-supply so ingconsxructed and combined to f q present a wrapper to the wrapping inecha forming the wrap ping operations; It has v in neral, to supply the'article: orarticles 4 0 the carrier.

The .functionsof the wrapping mechanism are, in general, to receive a wrapper from the Wrapper-supply mechanism, and receive from the article-su ply mechanism the article or articles to inwrapped, 'inclose the saidarticle or. articles in the said wrapper, and complete the inwrapment thereof. .1 In its broader phases, the invention is not restricted with respect tovthe precise char- 3 acter, construction, and mode of operation of the wrapper-supply mechanism, or of the article-supply mechanism, or of the wrapping mechanism. Many forms of all these mechanisms, regarded separately, are known I in the art, including mechanisms which feed a continuous strip of material and then sepa-' rate itinto short lengths suitable for wrap-'v pers, and alsoincluding mechanisms which feed from a sta k of previously-prepared,

' wr pp r its broader phases-will be involved,-what-- 4 ever forms and th spirit of my invention in V of these various mechanisms are utilized in carrying the same into effect.

Referring now to the construction as illus trated in the drawings,

The carrier A is mounted by means of its hub 1 (Figs. 1, 2, 3) upon an upright shaft '2, and is rotated in convenient manner, as

for instance by engaging it "with the said shaft and rotating the latter by suitable driving connections (not shown). fA bearing for shaft 2 is shown 'at 3, i'n'Figs. 3

7 At each-'Wrappersupply? station, "the." 6 wrapper-supply.

mechanism is supported by a fixed arm 5, (Figs. 1, 2, 3, 4) forming a part'of the machine-framing, on which arm vthe said mechanism is mounted above the path in--.which the wrapping-head travels,

The wrapper-supply mechanism comprises a'pair of feed-rolls 6, 6, means for rotating guides 7, 7, shears 8, 8", and means for ac-' tuating the movable member of theflsaid shears.

The feed-rolls are mounted suitable the said feed-rolls, upper and lower strip stands 6, 6; The continuous strip of wrapper-material passes between the feed-rolls, and is advanced or fed through the stripgmdes and between the shear-blades by the rotation of the feed-rolls, being thereby drawn from a conveniently located supplyroll (not'shown). The feed-rolls are geared hearing at the top of one of the stands 6,

A. convenient form of devices for effecting. the shift or adjustment of carriage 9 upon arm 5 comprises theracks 9, 9, (Figs. 2 and 4) in fixed connection with the arm 5, pinions 9", 9", engaging suchracks, a shaft 9 on which said pinions are fixed, the

' said shaft extending transversely with reference to the carriage and being mounted in bearings 9, 9, thereon, and a thumb-wheel 9, (Fig. 2) u on the shaft 9, by means of which the slia t and pinions maybe turned manually, When the shaft isturned, the

' pinions travel alon the racks, and the shift 5 2'5 of the carriage is t ereby caused. The carriage is fixed in the position inwhich it has been set by the adjusting devices, by means of a clamping bolt 9. (Flg. 2) and wing-nut 9 The stem of the said bolt works in a slot 3. in a strip 9" attached to arm 5, and also extends througha hole in the carriage. Thehead of the bolt is located'beneath the strip 9' andwing-nut 9 is located above the, flat bed of the carriage. When the wing-nut is turned down tightl against the said bed, the latter is clampe to the said stripfl9" and inasmuch as strip 9 is fixedly attached to H arm 5, therebythecarriage is 'securedinad- .justed position. The slot in stri 9 rmits I p of thejbolt to move with t e car- .riiageiflu I v f At theart'iclesu ply stationD a support i 10 (Figs. 1, 2 an article or articles to be inwra ped, and from which the said article or articles (hereafter termed article) is'taken by the means with which .the wrapping-head is provided for that purpose, as the wrapping-head passes the said station. The said support is, in

this instance, a trough located above the path. in which the wra ping-head travels,

and inclined downward y. toward its forward end. It is mounted upon afixed support. An article deposited within said trough is swept or pushed along the same by a device whichpresently will be described, and passes downward from its lower. front end upon the wrapper held by the wrappinghead and bein carried around with the latter. 'Prefera 1y, automatic means of feeding successive articles to the support 10 is combined with the latter. A convenient'form of such means is shown, it comprising an endless flexible feed-chain 11 7 (Fig- 5) having projections 11, 11, and a 13, 13, at opposite sides of the said. rest. The

the upperrun of the said feed-chain work within the said slots or openings, and project above the rack or grate, so as to engage articles resting upon the latter and push them along the rack or rate, and deliver them successively to the support 10. The feed-chain extends around carrying wheels 11, 11", which are mounted upon a fixed support l1 (Figs. 1, 2, 5). The carrying wheel 11 has combined therewith driving mechanism comprising a bevel-gear 11 (Figs. 1 and .2) fixedly connected with the 30 said carrying wheel 11", a driving bevel-. gear 11' meshing with bevel-gear 11, a shaft ll 'on which the bevel-gear 11 is fixed, a second bevel-gear 11 also fixed on said shaft, and a bevel-gear 11 fixed on shaft 6 and in mesh with bevel-gear 11 Shaft 11 is .mounted in bearings in the fixed support 11". Anyother approved driving arrange-- ment for the article-feed chain or conveyer may be employed in practice. 1

The wrapping-head is furnished with a. receiver for the wrapper and the article which is to be inwrapped therein, the said receiver receiving the wrapper as the latter is taken at the wrapper-supply station,,and holding it in position while the article taken at the article-supply station is applied there- The receiver is provided with a rest .12, (Figs. 2, 3, 6) and side-jaws or pressers I said parts are mounted upon a'support'14, (Figs. 6 and 7) which inz turn is mounted upon the arm 40f the carrier. In the work-. ing of the machine, the receiver is turned to the receiver, the latter occupies its nor,-

mal position shown. in" Figs; 2, and 3. --It.

subsequently is given aquarter turn about portions of the wrapper to deviceswhich act thereon, and later by another turning movement is restored to its normal position. i

This turning movement of the receiveris provided for by forming the support with cylindrical portions 15, 16, .(Figs. 1,6,7), which are fitted to upright bearings in the .arm. The receiver is supported vertically by means of a radially projecting flange 17 (Figs. ,6 and 7), which rests upon the arm it comprises an arm 19 that is sleeved upon' l the lower portion-of the support 14, and fixed thereon, the said arm being joined by about a vertical axis and supported by a stu v 22 extendin downward from the arm 4, the

other arm 0 the said rocker beiniif-prnished g in the 18C groove 23' (Figs. 1 and 2) of a stationary cam-plate 24. Asarm 4 makes its circuit, the said anti-friction roll travels around within the said groove, the walls of which by their varying sha eoccasion' swinging movements of the roc er, which are transmitted to the receiver and occasion the required turningmovements of the latter. The rest 12 (Figs. 2, 3, 6) of the receiver is yieldingly upborne, in order that when the wrapper and the article to be wrap ed are received thereon, and pressure is app ied to the article to cause it to pass down into place between the side-jaws or pressers '13 13, the rest may yield to the pressure, an

automatically accommodate itself to articles 1 of difi'erent sizes. Also, in order that when the wrapping operations have been completed, and the side-jaws or pressers have been opened to relieve the now inwrapped article from restraint, the rest may rise to its normal position, lifting the wrapped article out from between the sideaws or ressers, to a position above the latter. In

igs. 6 and 7 the rest is'mounted upon the .upper end of a spindle 25, the lower end of which works within a tube 26 contained within a post 27 rising from the upper portion of the support 14. An expanding spiral spring 28 is confined in the said tube, be-

tween the lower end of the said spindle and a plug29 occupying the lower end of the tube. The spring acts with a tendency to keep the rest 12 normally in its elevated position at the top of the side-jaws or,

pressers 13, 13. A cap 30 at the top of post 27 limits the extent of the rise of therest, through engagement with the shoulder, at the top of the enlarged lower end of the spindle 25. a

The side-jaws or pressers 13, 1 3, (Figs.2,

3, 6, 7) of the receiver comprise opposite clampin members carried b levers 31, 31, ('Fig. 6? which are 'pivote at 32, 32,. to the support 14. For the actuation of the .side'jaws or pressers the lower arms of the the wall levers 31, 31, respectively have pivotally connected therewith the outer ends of links 33, 33, the inner ends of which are joined by a pivot to the upper end of an endwisemovable plunger 34. The said links, throu h' their connection with the levers and with t e plunger constitute a toggle.

An expanding spiral spring'35 is compressed between a I the chamber. This ,ency to, move the p draw downward the joint of the oggle, so

lunger works in a central unger downward, and j the engaging portions of the side-jaws or pressers 13, 13.. Through the action of the spring, the side-jaws or pressers normally are kept in their most widely opened POSI- tlons. For the purpose of moving the sidejaws or ressers toward each other, an artic e lying between them on the rest 12, the plunger is actuated to move the same upward against the resistance of thespring 35. The means of causing the upward movement of the plunger may vary in practice. Herein, a lever 26 (Figs. 3 and 7) is pivoted at 37 to a small bracket 38 extending down from arm 4. 01 1e arm of the said lever engages with the plunger, while the other carries an anti-f: 'iction roll 39 which travels upon the upper surface of the stationary cam-plate 24. A raised portion of the campath 40 for the 1011 39 swings the saidlever 36 upward at the proper time, and thereby to clamp moves the plungi =r upward so as to straighten j I make provision for avoiding too greata degree of pressure of the side-jaws or pressers 13, 13, upon the piece of candy or other article and i wrapper between them. To this end I make provision for securing a yielding action 01? the side-jaws or pressers 1n closing toward each other. 7 Such provision or provisions may be variously located in connection with the side-jaws or pressers and their suppor ting and operating parts and devices. 11 Figs. 3, 6, 7, the side-jaws or pressers 13, 11;, are connected with the carrying levers 3t, 31, therefor by pivots 41, 41, and receive the pressure of leafsprings 42, 42,;which are attached to the carrying levers 3], 31, the said leaf-springs operating with a tendency to cause the sideaws or pressers to turn toward each other on their pivotal connections with the carryin levers and to hold tail-portions 43, 43," ig. 6) of thesaid side-jaws or pressers in engagement wit h the inner surfaces of the upper portions of the carrying levers. The relief arrangement thus constituted obviates damage. to candy which is liable to be crushed by undue pressure, and also obviates tendency to produce undue adhesion of the wrapper to candy of a sticky nature.

To insure proper engagement of pressers with the opposite side-portions of and the. desired action of the said jaws in holding the side-portions of the closely flwite sides of a piece of candy. or otherf'article lying upon the wrapper, the throw of the actuating devices for the side-jaws or pressers'is madesuflicientlygreat to cause such versely which the m'achineis intended jaws to close together to the extent 'required for coiiperation withe piece of candy or other article of the smallest size trans- V handle, the relief-contrivance yielding. to

As soon as the article; has been deposited upon the wrapper carried by the wrappinghead, it is acted upon b a Presser-device .by means of which it an the wrapper and the table 12 upon which the article and movement of the wrapping-head past the Means is provided for causing at the assing over the feed-rolls'and cutteras' passed the -next-' wrapper-supply wrapper rest aro caused to descend between the workingfaos of the side-jaws or pressers 13, 13. In the present embodiment of the invention tte presser-device is a finger 727(Figs. 2 and 3) which is carried by an arm 73, pivoted at 56 upon the arm 4 of the wrapping-hard, and operated through connections and devices resembling those which are combined with the carrying-arms of the fingers 5t and 66. That is to say, the arm 73 has pivotally connected therewith the upper and of a link 74 havingits' lower end p1vot illy connected with the upper end of a rod 75 adapted to slide up and down in a fixed. guide in-connection with the arm 4 and carrying at its lower end an anti-friction roll or 7 6 traveling upon a fixed cam' 77 in connection with the fixed plate 24. The raised portion of the said cam 77 acts to raise th earm 73 and the presserfinger 72, and holds" them normally raised in the position in whichthey are shown in Fig. '7 3, so as :0 clear the Wrapper-feed mechanism in passing the latter, the said cam beingso shaped as to allow the presserfinger 72 to descend upon the article as soon as it has landed in place upon the wrapper,

and by pressurr thereon force the rest 12, wrapper, and article down between the sidejaws or presser: 13, 13. A suitable spring (notshown) is operatively'combined with action. Other s rings (also not shown) are employed-in practice, to insure the descent of finger 54- and finger or sweep 66. f As the rest 12, wrapper, and article are .the presser-finger to assist in producing this pressed down between the side-jaws .or pressers 13, 13 Pin the manner ust explained, the upp :r ends of the said jaws support the side-pt rtions of the wrapper, and consequently such side-portions are turned upward as a re sult of the article and the middle portion f the wrapper being pressed downward betwl :en the side-jaws or pressers. Normally, the yew-devices occupy the position in which th :yare represented in Fig. 2, namely with the opening between the jaws or pressers sentedin the direction in whichthejaw-cevices are traveling. As a result of this, one end of the doubled-up wrapper is presented in the direction in which the wrap'iing-head istraveling.

I cm loy devices by means of which one upstan ing side portion of the wrapper is turned down up on the article and then the other upstanding; side-portion is turned over -the twisting while traveling. Each twister consists of a pair of jaws which at the proper time close upon the corresponding pro ecting end-portion of the wrapper which has been folded into tubular shape about the inclosed article, the closing operation serving to gather the sides of the tube t I her,

and the rotation'of the twister opera, g to comprem the portion of the wrapper that is grasped b the jaws, and also twist the endportion 0 the wrapper, making one or more turns in such end-portion at and adjacent theplace that is inclosed by the jaws. For greater simplicity and convenience the construction of the machine, the two twisters are located in line with each other radially of the rotating portion of the machine, and at opposite sides radially of the holdingjaw devices. ating mechanism are shown combinedwith the machine in Figs. 2 and3 and separately in Figs. 10 and 11, Sheet 6 and Figs. 13, 14, 15, Sheet 5. Each twister comprises a pair of jaws 90, 90, upon the extremities of arms 91, 91,. carried by the twister-head 92. The

said twister-head is formed'with a, sleeve I which is mounted to turn in bearings 93, 93,

forming a part of the arm- 4, and for the. purpose of rotating the twister-head a spurpinion 94 is fixed upon the said sleeve between the bearings 93, 93, such pinion being in driving engagement witha spur-gear 95 fixed on a radial shaft 96 (Fig. 3, and Figs.

10,11, Sheet 6) supported in bearings 97, 97, in connection with the arm 4, the said shaft being driven by means of -a bevelwheel 98 fixed thereon, a bevel-wheel 99 with which wheel98 engages, an upright shaft 100 on which the bevel-wheel 99 is fixed, the said I upright shaft turning in a bearing carried by the arm 4, and a spur-pinion 101 (Fig. 3) fixed on the lower end of the said she 100*and engaging with a rack 102 on the outer edge of the fixed plate- 24. As the wrap ing-head travels around,

the engagement 0 the spur-pinion 101 with the said fixed rack 102 causes suchispurpinion and the shaft 100 and bevel-wheel 99 to rotate, and from the said bevel-wheel the radial shaft 96 is rotatedthrough the connections described. The two twisters are driven from the opposite ends of the radial- B0 shaft 96 through a duplication of the driving-connections 94, 95.

- mounted in connection-with the twister-head I The arms 91, 91, of a twisterare pivotally 92. They occupy normally an open retracted position, such, for instance, as that The twisters and their actu-' circular toothed in which they are shown in Figs. 2, 3, 10, 11, 13. They are adapted to swing from this position into one in which the jaws 90, 90, areclosed together as in Figs. 14 and 15, Sheet 5, and are causcd'to swing back into the open position again. The twisters have a continuous rotary motion and during such rotary motion are close at intervals for the purposes of the twisting and then opened again. The means of operating the arms and jaws of the twisters to close and open the latter may'vary in practice. Herein, I have shown a simple construction of operating devices comprising pinions 104, 104, on the pivots 103, 103, of the arms 91, 91, an axiall disposed rackbar 105' contained within t e sleeve of the twister-head and engaging with both of the said inions, and means for moving the said rackar longitudinally in the proper directions to close and open the twister-jaws. The rack-bars of the two twisters are operatively combined with the same train of mechanism, whereby they are actuated simultaneously. Thus the rack-bar of the outer twister is provided with a grooved. collar 106 engaged by a forked arm 107 connected to turn in unison with a cam-operated lever-arm 112, both being fixed upon an upright rockshaft113 near the inner end.

of arm 4, the said rockshaft having fixed thereon a forked am 114 engaging with a grooved collar 115 on the rack-bar of the.

inner twister. The upright rockshaft 113 is mounted to turn in bearings in connection with the arm 4, the arm 112 at its lower end being provided with a roll or pin 112 (Fig. 11) working in a cam-groove, 112", (Fig. i

2) in the fixed table 24. The said camgroove is so shaped that it actuates the described devices, and through the forked arms and the grooved collars engaged thereby,

moves the rack-bars lengthwise at the proper times, and in the proper directions to close and open the twisters as required. .To render the action of the jaws 90, 90, yielding inclosing upon the vvwrapper so that they may accommodate themselves to the bulk of the portions which they embrace, and clasp the same tightly yet without crushing-or cutting the wrapper, provisions for securing the yielding action are interposed at proper points. In the present instance the I grooved collars 106, 115, are movable l en b5 wise upon the rack-bars, and expan ing spiral springs 123, 123, are .confined between such collars and fixed collars 124,

124, u n. the rack-bars. The springs in expan ing tend to hold the collars 123, I 123, against'other fixed collars 125, 125, on

' the rack-bars. The force which trans mittedthrough the forked 'arms to the grooved collars tending to move the rackbarsin the ;direction toclose the jaws of the twisters upon the wrapper, acts through the springs and hence is-"transm' yielding manner to the". rack-bars through themand the spur-pinionsthe arms and jaws of the twisters.

- The twisters preferably are mounted with capacit for adjustment toward and; from each ot er, so that the intervening distance may be varied to suit different lengths. of

articles. This adjustabilit may be provided for in various ways. 11 the illustrated instance the sleeves 92, 92, are capable of be? in shifted lengthwise toward orfrom each I at or through the eyes 'or centralo enin'gs of the actuating spur-gears 94, 94.

them to turn in unisonwith the said spurgears, the sleeves are furnished with longitudinal splines 92392 (Fig.,10) engaging I ,Wlth the spur-gears. twisters toward and from each other is efl'ected in this instance by means of adjustnut 128 working upon a screw-threaded 'l he adjustment of the ing devices in engagement with both sleeves,

andvacting tomove the twisters simultaneously either toward each other or away from each otherc For the purposes ofthe said adjustment, each sleeve 92 is furnished with a grooved collar 92,and forked levers 126, I

126, engage with suchcollars. -'l hese levers are mounted by vertical pivots at 127, 127, (Figs. 11 and 12), upon xed portions of arm 4, so that they are capable of'a swinging movement toward and from each other. Each has connected therewith pivotally a portion of an-ad'ustingshaft 129. The opposite threads 0 the said shaft are, respectively, right-and. left handed. A grooved collar 130 upon 'said-shaft'engages with a fork 131 in connection with-arm 4, such fork serving to prevent m ovement of the shaft e'ndwise; The'shaft is furnished with a handle" 132 for convenience in turning the 1 same.

When the shaft is turned, the nuts 128, 128, are screwed toward or away from each other, as the case may be, and thereb the levers 126, 126, are swung so as to shi the twisters toward and from each other, as

f required. :The vertical rockshafts- 108 and 113 are mounted in bearings provided in connection with the levers 126, 126, so that such .rockshafts'acconixpany the said levers in the movement of ustment of the latter, and in consequence of the engagement of roll 112 with the walls of the cam-groove varied materiallyby reason o the adjustin which it .worksthe rack-bars are-automatically shifted so that the extent to which the jaws of the twisters are 0 ened is not ment.

In the broader phases of the invention the latter \is not restricted with respect to the tively long j aw-a ems, 'althoug scribe-a small 011016111 rotating when open. 0 'cause particular mode of mounting the twisterjaws upon the tw .ster, or to xthe specific construction of the twister and its aws. Certalnparticular features of the invention,

however, comprire :a' novel mode ofmounting, and] a novel construction, bymeans .of

which novel and improved results are attained. The said. novel mode of fmounting' consists in locati rig the pivots of-the 'aws;

of a twister at opposite sides of theexls 'of j rotation-of. the twister, extending-the arms of the aws in op osite directions across such axis, and dlSPOSL mg each jaw at the side of" such axis'opposit rthat at which its pivot is located. This is :learly. shown in the draw ings. This enables me to emplttig comparajaws dei It also results it. causing the jaws tocontinue to ap roaci moreclosely to the ends so that ample sp roe for the accommodation of the expanded and of a wrapper may be provided between theclosed-together jaws and the twister-head. r

As will be perc aived from 13 and 14, j Sheet 5', the twister jaws have V-shaped f ofthe artic e as they closejtogethen. It-furh their. permits the employment of long arms, i

notches, and as the jaws close together the oppositely projezting horns of the jaws gather in the portion of wrapper projectmg beyond the article inclosed thereim'puck ermgit together closely in a bunchfgathered-in equally f1 em all sides? The 'portion thus gathered in is twisted close to'the end of the article by the rotation of'the twister,

this action takirg place simultaneously at opposite ends of the article. Inthe case of each jaw of a twi ;ter,.one of the hornsthereof is oflset or set askew withrelation tothe other horn there )f, and when the two jaws of the two jaws: of a twister produces 'a lot of the wrapper. away from the correspond-g ing end of the i1 iclosed article. The conditions are reversed in the case of the two twisters, so that the opposite end-portions of a wrapper are drawn len hwise 1n oppo- 'i site directlons avayfrom t 'e inclosed'article, thereby cat sing the wrapper to fit snugly about the said article, eliminating slaokness or loose ness of thewrapper.
